I don't think you have to click through the pointclick site to make purchases that qualify for rebates. I certainly didn't see any mention of this on their site. Just bought a case from OnVia yesterday, filled out the rebate form today, and had $9.20 added to my "pending rebate check."
Here are the details the list for claiming a reimbursement:
PointClickers will now enjoy 10% cash back on everything purchased on The PointC1ick Network (sites that are specified as reimbursement sites). That's in addition to any Merchant discounts, promotions and cash earned from surfing PointClick! Here's how it works:
Purchase a product from a participating Merchant site in The PointClick Network.
Complete and submit a reimbursement form.
Forward the confirmation e-mail from the Merchant showing that you indeed purchased the item to confirm@pointc1ick.com or fax it to 801.760.0688.
Receive any reimbursement money you are eligible for PLUS the 10% cash back in a check.
I dunno--does "from a patricipating Merchante site in the PC Network" mean I have to click THROUGH their site, to the retail site, then make the purchase? Very vague, very ambiguous. What a horribly, horribly documented site.
Bah.
